Question

​2/3 cộng 4/9 trừ x = 5/6

Answer 1

NÀY HẢ BẠN ƠI:

\(\frac{2}{3}+\frac{4}{9}-x=\frac{5}{6}\)

\(\frac{10}{9}-x=\frac{5}{6}\)

\(x=\frac{10}{9}-\frac{5}{6}=\frac{5}{18}\)

k mk nha

Answer 2

\(\frac{2}{3}\)+ \(\frac{4}{9}\)- \(\frac{5}{6}\)

= \(\frac{12}{18}\)+\(\frac{8}{18}\)- \(\frac{15}{18}\)

= \(\frac{20}{18}\)- \(\frac{15}{18}\)

= \(\frac{5}{18}\)

Chúc bạn học tốt

Answer 3

\(\frac{2}{3}+\frac{4}{9}-x=\frac{5}{6}\)

<=> \(\frac{10}{9}-x=\frac{5}{6}\)

<=> \(-x=\frac{5}{6}-\frac{10}{9}\)

<=> \(-x=\frac{-5}{18}\)
